The list now includes people who are “deemed to be a threat to national security” or who “have gone to terrorist training camps.” Previously it included only people who represented “a specific threat to take down an aeroplane.”

Underwear bomber Umar Farouk AbdulMutallab wasn’t included on the list even after his own father reported Umar to the U.S. Embassy in Nigeria.

According to CNN, “…AbdulMutallab’s father was a respected businessman and would have been viewed as a credible single source under the new procedures. The official said all the changes are evidence the listing process has ‘matured.'”
